New build - need equipment help please

16 x 36 fiberglass rectangle - 18k gallons
3 returns - 1 skimmer, no floor drains
2 inch rigid PVC plumbing
1 18 inch waterfall - may add another
PLM150 Pentair PLM Series Cartridge Filter (150 sq ft)
Omnilogic automation
considering the T-Cell-15 but not sure due to travertine coping

With the omnilogic, Hayward told me I have two choices. The Tristar SP3202ND or the Ecostar SP3400VSP. I would choose the Tristar because I think the Ecostar is way more pump than I need, but the Ecostar is the only Omnilogic compatible pump with it own controls in case the Omnilogic is on the fritz. I don't want to be without ability to filter the pool if the automation glitches.

I plan to add on the aqua comfort ACT-1250 Heat/Cool pump in short order.

The install is second week in June and I have to finalize equipment choices asap.

Does anyone have any feedback on selections and how the filter and pump will match up for optimum filtering?

Thanks guys.

Ugh. Wish I could help!

I would double the size of your filter. You won't be sorry.

Also, did they tell you that the MaxFlo VS would not work with the OmniLogic?

Also the Tristar comes in a version that has the builtin timers as well if you want to go that route.
